The Radium Engineering Fuel Pump/Fuel Filter Dual 60mm Clamp (20-0122) allows you to mount any fuel pump or filter that has an outside diameter of 60mm. The Radium Engineering Fuel Filters are a perfect fit as well as Bosch 044 and similar fuel pumps. The clamp is made of 6061 billet aluminum and mounts directly to the body of the filter/pump improving thermal efficiency. A stainless steel M8 bolt and lock nut is included. This clamp must be mounted to a flat surface that has a M8 countersink. The clamps are bright-dip anodized Radium green with laser engraved logos. Because the clamps are thinner, it is highly recommended to use to clamps to secure fuel pumps as pictured below.
